Outline of Final Research Achievements

Photofunctional materials which show switching of circular polarized luminescence (CPL) by external stimuli are expected for applying as various chiroptical materials. In this study, we tried to create novel functional composite material enabling CPL modulation through electrochemical reactions.
By using chiral Eu(III) complex and electrochromic viologen molecule,red CPL from the Eu(III) complex was modulated via electrochemical coloration of viologen molecule. Moreover, effective CPL modulation was successfully demonstrated by introducing viologen derivative with coordination moiety for interacting to Eu(III) ion.
